Next week I am moving a 90g established tank to a 150g tank. Need advice on how to move everything over. Do I need to recycle the 150g? I'll be putting in new sand. Can I transfer water from one tank to the other?

Ya put the water from the 90 in buckets then fill the 150 and add water as needed. Why dont u just use the old sand? After the waters out of the 90 just scoop it up. Also, put the fish and the rock in the buckets until the 90 gals is in the tank. Dump the sand in 1st. I did the same thing with my 75 into 150. Good Luck!!!!!

Good luck??? That doesn't sound promising.... Lol.. Ok, I'll do that... You have any spikes after u got done?

Its really not that big of a project..I would personally get new sand and just use a cup full or 2 of your old stuff...I have done this a few times and i even used all new water...As long as all the LR and all the filtering from the 90 is going directly into the 150 you'll be just fine

I am. Just making a bigger sump. And I'll be getting a new light... Lol. Thanks for the advice.

When I did my 55g to my 125g I started with all new sand. I put in thenew sand, added the saltwater and then setup the sump. I let it run a few days to get any clouding down, which luckily I didnt have much of.

I then moved the majority of my rock over and left some in with the fishies. After a few more days I did the big move with the rest of the live rock and the extra base rock I had ordered. I left a little of the water in the 55g and slowly caught my fish, acclimated them and in they went.

I did have a 3 day ammonia spike though between initial filling with the majority of the live rock and the refugium contents that came from my pod tank I had cgoing. thats why I let the fish stay in the 55g without much rock, to wait out the ammonia.

It took me several hours to get everything moved over but it wasnt too traumatic and I did pretty well.

At least til I added new fish a week or two later and it all went downhill. But thats another issue. Maybe my tank wasnt ready for the new additions so soon after the move or most likely one of the fish I added had an issue. I was not qt'ing then.

I have a mix of many different saltwater fish amongst my tanks, but I love my Tangs most of all.

I have no idea, I'd guess a day. Though keep in mind that your live rock does do the majority of the filtering in the tank and with proper flow should continue to do its filtering. But I would probably move quicker than I did. But then you risk spikes. Are you going to be adding more base rock? You can start your new tank with just that and then move all live rock and fish the same day after you get the sump up and running.

Sorry, I totally didnt think about the one sump thing. I was lucky then I guess that I had the luxury of time.....
